Application filed June .14, 1924. Serial No. 719,919.

This invention aims to provide an improved stud and socket fastener of the pushbutton type.

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 is a front-elevation of the preferred form of fastener;

Fig. 2 is a rear elevation of the stud attached to a curtain;

Fig. 3 is a section, partly in elevation, on the line 3-3 of Fig. 1. showing the stud slightly entered within the socket;

Fig. 4 is a section similar to Fig. 3, showing the stud entered further into the socket;

Fig. 5 is a section similar to Fig. 3, showing the stud locked within the socket;

Fig. 6 is a section on the line 6-6 of Fig. 5; and

Fig. 7 is a front elevation of the socket attached to the body of an automobile. Referring to the drawings, 1 have shown a stud attached to a curtain 9 by means of prongs 11 projecting from a front plate 13 and engaging a back plate 15 substantially as more fully illustrated and described in the co-pending applicationofiled herewith, Serial No. 719,917. I Y

The preferred form of stud, as illustrated, presents a socket-engaging member 17 pressed from a base 18 and provided with slots 19 to permit contraction and expansion of the socket-engaging member when engaging or disengaging a socket. This -member is preferably secured to the front plate 13 substantially as illustrated and described in the above-mentionedapplication WVhile the socket-engaging member 17 may be secured to a socket and held in engagement therewith by its own resiliency, I prefer to provide locking means 23 for lock ing the socket-engaging member against contraction when engaged with a socket.

The locking means 23 comprises a press button 24 presented at the face of'the front plate 13 and a locking head 25 normally extending beyond the socket-engaging end of the socket-engaging member 17. The locking means is held in normal position by a spring 27 interposedbetween a flange 28, located upon the locking means, and the front plate 13.

The flange 28 also limits the forward movement of the locking means by engagement with the shoulder or adjacent the neck of the sachet-engaging member 17.

The preferred form of socket includes a casing 29 secured to the sheet metal side 30 of an automobile by a plurality of prongs substantially as shown and described in the above-mentioned co-pending application. This casing presents a stud-receiving aper: ture normally closed by a sealing. disc 31, which is urged into aperture-closingposition by a spring 33 substantially stronger than the spring 27 located in the stud.

The stud may be engaged with the Socket by pressing upon the front plate 13 thereby urging the study toward the aperture in the socket. Because the locking head 25 is normally beyond thereversely bent portion ofthe socket-engaging member 17, the head of the socket-engaging part may contract and enter the aperture in the socket without interference from the locking head, as-best illustrated in Fig. 3I The sealing disc 31 is provided with a depression so that the locking'head 25 may pass through the studreceiving aperture and into the depression without engaging the sealing disc during initial contraction of the head of the stud. Thus, when the stud is moved into full engagement with the socket, the locking head is excluded from engagement with the reversely bent portions 35, and the locking head 25 engages the sealing disc 31 and forces it inwardly against the pressure of the spring (Fig. 4) until the head of the stud has passed through the stud-receiving aperture and again expanded to its normal position. The strong spring 33 then urges the locking head 25 into engagement with the reversely bent portions 35 against the pressure of the weaker spring 27, thereby locking the stud and socket together and preventing accidental separation thereof, as best illustrated'in Fig. 5.

Separation of the stud from the-socket may be elfected by grasping the lower edge of the curtain and exerting a slight outward pull thereon, at the same time pressing the press-button to displace the locking head 25 from engagement with the reversely bent pprtions 35 of the socket-engaging member 1 7 WVhile I have shown and described a preferred form of one embodiment'of my invention, it will be understood that changes involving omission, substitution, alteratien and reversal of parts, and even changes n the mode of operation, may without r departing from the scope of my lnvention, which is best defined in the following claims- Claims:
